When you work out a carbon footprint(碳足迹)，a lot of factors are taken into consideration. For example, driving to the grocery store bums a certain amount of fuel, and fossil fuels are the primary sources of greenhouse gases. But that grocery store is powered by electricity, and its employees probably drive to work, so the store has its own carbon footprint. In addition, the products that the store sells were all shipped there, so that must also be factored into the total carbon footprint. Beyond that, the fruits. Vegetables, and meats that the store sells were all grown or raised on farms-a process that produces methane(甲烷)，which has a greenhouse effect 25 times greater than CO. All of those elements must be combined to understand the full carbon footprint of a given activity.
Although adding up one's own carbon footprint can be difficult, online calculators can do some of the work for you,giving a rough estimate(估算)of your carbon footprint based on the size of your household, the efficiency of your machines, how much you drive or fly, what you eat, and how much you recycle
This isn't perfect, but it is a good way to measure your activities so you can know roughly how much CO2 they produce and take steps to reduce your carbon footprint.
Methods of reducing your carbon footprint include driving more efficient vehicles (or making sure that your current vehicles are properly maintained), taking public transportation, using energy efficient machines, building your home with special materials to reduce heating and air conditioning costs. consuming food that doesn't require as much transportation, and eating less meat which has a higher carbon footprint than fruits and vegetables. People and companies can also offset some of their CO2, emissions(排放)by purchasing carbon credits, the money from which can go into projects such as planting trees or investing in renewable energy.
